Application filed September 4, 1914. Serial No. 860,156.

To all whom it may concern Be it known that we, MICHAEL PowLowsm and STEPHEN A. MISCHANSKY, both subjects' of the Emperor of Austria-Hungary, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Horseshoes, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improve ments in nail-less horse-shoes, involving the use of a lower plate for the shoe proper to support the hoof, and an upper band adapt-. ed to be clamped around the hoof and to which the lower plate is detachably secured.

7e are aware that similar devices have heretofore been proposed in which the shoe proper was of special construction to conform to the specific construction of the hoofclamp and the object of our present invention is to permit the use of ordinary stock shoes for the lower plates and to fasten such shoes to the clamping band by screws or bolts which are accessible for loosening or tightening the shoe without lifting the horses hoof, or removing the band.

Another object is to provide the clamping band with a roughened inner face to grip the surface of the hoof with greater firmness and thereby hold the entire shoe against displacement without mutilating such hoof.

A further object is to make the clamp as light as possible without sacrificing its strength by reducing the vertical width of the sides and providing extra width at the toe and heel where the strains are greatest.

Other objects and uses will be brought out in the following description.

In the drawings, Figure 1 is a perspective of our improved horse-shoe, showing a portion of a horses hoof in dotted lines. Figs. 2 and 3 are respectively longitudinal sectional view and a transverse sectional view of the same shoe taken on lines 2-2 and 3-3, Fig. 1. Fig. 4 is a top plan of the lower plate or shoe proper. Fig. 5 is an inverted plan of the clamping band by which the lower plate is held to the under side of the hoof.

This horse-shoe comprises a lower wearing plate -1 and a clamping band 2--, which for lightness is preferably made of sheet metal, to conform to the shape of the hoof except that its rear ends are reinforced for receiving a clamping bolt 3 by which it may be tightened upon the hoof, the lower portions of the sides of theband being also reinforced or pressed outwardly at intervals to form lugs -'l having flat upper faces and vertical apertures for receiving screws or bolts -5- engaging in registered threaded apertures in the lower plate --1- whereby the two members 1 and 2 are detachably secured to each other, the heads of the bolts 5 being engaged with the flat upper facesof the lugs 4--and are always accessible for engagement by a screw driver or equivalent tool in tightening or loosening the lower plate without lifting the horses hoof or displacing the clamping member The lower plate -1 is preferably an ordinary stock-shoe having a flat upper face throughout its area and of suiiicient width and length to form a support for the bottom of the hoof and to extend slightly beyond the marginal edges thereof for receiving and supporting the lower edges of the clamping band -2. This band is made to conform to the shape and outline of the hoof, and in order that it may efi'ec tively hold the lower plate in operable positiomits front and side walls incline upwardly and inwardly to fit snugly against the corresponding portions of the hoof, the lower face of said band being disposed in a flat plane coincident with that of the upper face of the lower plate, so as to fit snugly thereagainst at all points throughout its length. The rear ends of the band are spaced some distance apart and are apertured for receiving the bolt -3- by which the entire band may be drawn tightly around the hoof or loosened when it is desired to attach or remove the band.

In order that the band may be as light as possible without sacrificing its strength, the greater portion of its opposite sides are comparatively narrow vertically and the upper edges of said portions are substantially parallel with the lower edges, but the toe portion is provided with an upwardly extending flange -6 to better resist relative forward and rear movement of the hoof and shoe and to afford the desired clamping efiiciency where it is most required. For a similar purpose, the rear ends of the sides of the band are provided with upwardly and forwardly projecting flanges -7-- to afford additional bearing on the hoof, thus producing additional gripping efficiency to prevent vertical or" lateral displacement of theshoe Where the strain is also excessive.

The entire inner face of the band is roughened at 8 in a manner similar to that of a file, so as to produce greater gripping efliciency on that of the hoof 'ior holding the clampi'ngband in p'la'c'e irrespective of the lower plate '1'", or shoe and -7- may be bent slightly to establish a firm grip thereon When the clamping bolt -3 is tightened a'fter which any ordinary stock-shoe of suitable size provided with the necessary screw holes may be quickly applied to the underside of the-band by simply tightening the screws 5 and When the lower plate b'ecomes :WOr-HOI other- Wise impaired, it may be quickly removed and replaced by a new one ithout disturbingtli'e' band;

What We claim is :v

A horse-shoe comprising a lower plate, having its upper face flat throughout its area a clamping band having upwardly andiiiwardly' inclined Walls provided With series of externally projecting apertured lugs and screws passed through said lugs and engaged with the 'lOWEI plate, said band having its rear ends' spaced apart and provided with apertures,-an-da clamping bolt engaged with said apertures.

In Witness" whereof We have hereunto set our hands this 2nd day oiz' September, 1914;.
